Abstract
The utility model relates to a countersunk screw word groove processingequipment mainly comprises the tight locating piece of clamp, countersunk screw group, copper sheet, sems. Pressing from both sides tight locating piece and being three -dimensional rectangle structure, middle relevant position is provided with the step hole for countersunk screw's installation. Countersunk screw group fix in that to press from both sides tight locating piece middle bench downthehole through sems. The copper sheet is strip arc structure, sets up pressing from both sides the downthehole below relevant position of tight locating piece step. The setting of sems cooperations screw hole is pressing from both sides at tight locating piece below. The utility model discloses a countersunk screw word groove processingequipment makes simply, and the cost of manufacture is low, and the cycle is short, the assembly installation is simple, and easy operation is easy, machining dimension is stable, can batch production.
Description
Technical field
The utility model belongs to mechanical manufacturing field, particularly a kind of sunk screw flat recess processing unit (plant).
Background technology
Flat recess sunk screw, as a kind of conventional criteria part, is applied to every field; Under the circumstances that instructions for use is not high, the processing normally upsetting system together with countersunk head of flat recess, but at the position that some are special, as Aeronautics and Astronautics field, because relatively stricter to the requirement of size, outward appearance, and the negligible amounts once ordered, raw-material hardness comparatively high, if continue to take the mode of upsetting to process, first because material is comparatively hard, device is caused to wear and tear more serious; Next is because each lot-size of aeronautical product is few, kind is many, therefore each specification needs the upsetting device of design specialized more; In addition, due to the competition fierceness all the more of mechanical processing industry, for guarantee company survives in keen competition, the presentation quality ensureing product is also needed when ensureing product mechanical performance; Comprehensive above factor, the product directly taking the mode of upsetting to process not only outward appearance can not meet the requirement of quality control, also because of the specificity of device, life-span short feature, can improve processing cost.
Utility model content
For solving the problem, the purpose of this utility model is to provide a kind of carry out sunk screw at batch and adds man-hour, clamping and dismounting can be carried out fast, improve the uniformity of sunk screw processing dimension, improve the quality of sunk screw and the sunk screw flat recess processing unit (plant) of production efficiency
A kind of sunk screw flat recess processing unit (plant), primarily of clamping and positioning block, sunk screw group, copper sheet, set screws composition.Clamping and positioning block spatially rectangular configuration, middle relevant position is provided with stepped hole, for the installation of sunk screw.Described sunk screw group is made up of 6 ~ 8 sunk screws, is fixed in clamping and positioning block middle bench hole by set screws.Copper sheet is strip arcuate structure, is arranged on relevant position, below in clamping and positioning block stepped hole, act as protection sunk screw bar portion and is not weighed wounded, sunk screw arbitrarily movement when can prevent clamping.Described set screws is made up of 6 ~ 8 screws, and each screw fit sunk screw is arranged on below clamping and positioning block, plays the role of fastening.
The utility model sunk screw flat recess processing unit (plant), manufacture simple, cost of manufacture is low, and the cycle is short; Erection is simple, easily simple to operate; Processing dimension is stablized, and can produce in batches.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model sunk screw flat recess processing unit (plant);
Fig. 2 is the left view of the utility model sunk screw flat recess processing unit (plant).
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of sunk screw flat recess processing unit (plant) as shown in Figure 1 and Figure 2, forms primarily of clamping and positioning block 1, sunk screw group 2, copper sheet 3, set screws 4.Clamping and positioning block 1 spatially rectangular configuration, middle relevant position is provided with stepped hole, for the installation of sunk screw.Described sunk screw group 2 is made up of 6 ~ 8 countersunk screw hole, is fixed in clamping and positioning block 1 middle bench hole by set screws 4.Copper sheet 3, in strip arcuate structure, is arranged on relevant position, below in clamping and positioning block 1 stepped hole, act as protection sunk screw bar portion and is not weighed wounded, sunk screw arbitrarily movement when can prevent clamping.Described set screws 4 is made up of 6 ~ 8 screws, and each screw fit sunk screw is arranged on below clamping and positioning block 1, plays the role of fastening.
The utility model sunk screw flat recess processing unit (plant), adopt the conical surface location of sunk screw, clamped position is bar portion, such advantage is: make shape because the conical surface is generally device upsetting, therefore uniformity is better in one batch, adopt conical surface location to can be good at ensureing the uniformity of positioning datum, thus ensure the depth dimensions of flat recess.By set screws 4, copper sheet 3 and sunk screw group 4 are fixed complete can processing.
The utility model sunk screw flat recess processing unit (plant), manufacture simple, cost of manufacture is low, and the cycle is short; Erection is simple, easily simple to operate; Processing dimension is stablized, and can produce in batches.
